“We are working in a field which we like to call Computational Geodesy. There, we are using methods and concepts from mathematics, statistics and informatics for the spatial and/or temporal analysis of large dimensional stochastic earth observation data. So far we focused on geodetic data sets, but we are interested in applying our approaches in more applications from geoscience. For this, the CESOC network is the perfect framework to establish new collaborations.”

“I am working on parallel algorithms to build and modify adaptively refined meshes at extreme scales, both in reference to the size of the supercomputer used and to the disparity of scales that arises in geophysical simulations. These algorithms are implemented and shared with the community via the p4est free software library that I have been lead authoring since 2007.

Within the CESOC initiative, my goal is to contribute theoretical and computational know-how on the efficient management of adaptive simulation topologies, mesh-related information, and geolocated data over general space partitions.”

Professor for Scientific Computing, Institute for Numerical Simulation, University of Bonn

“How do clouds evolve in a future climate? To answer this important question, we first need to understand the processes that lead to the formation, development and dissipation of clouds, in detail. Enormous progress has been made in recent years – due in part to new remote sensing methods from the ground, airplanes and satellites. Soon, a new generation of meteorological satellites will provide increasingly detailed insights into the complexity of clouds across the globe.

CESOC offers exciting opportunities to explore new paths for exploiting these novel data in a concerted action between computer science, earth sciences and mathematics jointly with people from observations and modelling.”

Prof. Susanne Crewell

Professor in Meteorology, University of Cologne

“CESOC is a great place for knowledge transfer. In my research, I focus on algorithmic techniques for geometric data analysis. I believe, algorithms research can open up new frontiers in climate science by providing tailored algorithmic techniques to attack computationally intractable problems. At the same time, the exchange with climate science researchers can bring to light fundamental algorithmic problems that are relevant in practice and require the development of new theory. Thus, CESOC feeds the development cycle and knowledge transfer between algorithmic theory and practice.”

“Predictions for the terrestrial water and energy cycle are of immense societal relevance. We develop complex models of the terrestrial system in HPC environments with extreme temporal and spatial resolution. With data assimilation techniques using in-situ and remote sensing observations we improve the models. Still, the development poses a big scientific and technological challenge – we address this challenge in the Centre for High-Performance Scientific Computing in Terrestrial Systems (HPSC TerrSys), with colleagues and students from the Geoverbund ABC/J. CESOC, together with ECMWF scientists and HPSC TerrSys generates enormous potential for synergies and innovation.”
